Mea Culpa – Dark Hours
Points and comments are a snapshot, not live.
Developer retracts and redirects domain after realizing his AI-built app copied an existing open-source project.
A developer launched "Dark Hours," a website built with Claude to show night-sky visibility. Another developer contacted him on Bluesky, pointing out the striking similarity-including bugs-to his own open-source project, DarkHours.app. The author investigated, concluded the AI had unknowingly reproduced the existing work, and decided to redirect the domain to the original developer. He apologized for irresponsible use of AI, admitting he relied on Claude without verifying originality. He also abandoned plans for an iOS port of the copied functionality.
What commenters are saying
Commenters largely praised the retraction as classy ethical behavior, with one noting this was the first retraction in 24 years of Daring Fireball. However, skepticism emerged about the "Claude did it" explanation, comparing it to other recent AI-ass-covering incidents (e.g., D'Addario guitar strings). Deeper digging revealed the original developer had also experienced an App Store rejection for an astrology app that later pivoted to astronomy-a fact the retracting author omitted, making the story more complex. Some argued personal responsibility for agents' actions remains, while others pointed out that LLM output isn't deterministic enough to accidentally clone bugs without significant prompting.
